基于模型和GIS的数字棉作系统的设计与实现

Design and implementation of digital cotton farming system based on models and GIS

为了进一步发展和完善棉花模型的综合模拟功能,提高其生产管理系统的机理性、数字化、可靠性和通用性水平,该研究运用软构件和参数化技术,决策支持与系统设计技术,结合GIS空间技术,充分发挥模拟模型的动态预测功能、GIS的空间信息管理功能、知识模型的管理决策功能,最终建立了基于数字模型和模拟分析的网络化数字棉作栽培管理决策系统,该系统以品种、气候、土壤、生产条件等数据作为基本输入,可为农业生产者、管理人员和科技人员等不同用户提供棉作区划、方案设计、模拟预测、实时调控、生产分析等棉花生产管理服务。系统的实现为棉花生产系统的数字化设计、精确化预测、动态化管理和网络化控制提供了支持。

In order to develop and perfect the integrated simulation function of cotton models, improve their management system levels of mechanism, digital, reliability, and wide-application, a digital and web cotton farming system based on model and GIS （Geographic information system） was developed by full utilizing the technologies of software component and parameter method, decision support and system design, GIS spatial technique, with integrating the advantage of prediction of simulation model, spatial information management of GIS technologies, decision support of management knowledge model. By inputting the parameters of varieties, climate, soil and production conditions, the system can set service for farmers, agronomists and researchers on farming zoning, cultivation strategy design, growth simulation, scheme evaluation, dynamic regulation and production analysis in cotton management, which provide digitalization, precision, dynamics, network services in prediction, design, management and control of cotton production system.
